M: Hey, Monica. What’s up? Looks like you go some sun this weekend.
W: Yeah, I guess so. You know,(9)I spent the weekend at the beach.
M: Oh, really? But it’s hard to find a hotel there. Where did you stay?
W: An old friend just moved there. She invited me for as long as I wanted to stay.
M: So what are you doing back here already? Didn’t you have much fun there?
W:(10)Oh, I have a paper to hand in this week, and I just couldn’t concentrate myself on studying at the beach.
M: Then what did you do out there, I mean besides lying out in the sun?
W: I played some volleyball. You know I never realized how hard it is to run on sand.(11)I couldn’t even get through a whole game before I had to sit down. It’s much easier to run in the wet sand near the water.
M: Interesting! Did you go swimming?
W: I wanted to, but they said the water isn’t warm enough for that until a couple months from now, so I just waded(涉水)in the water up to my knees.
M: Sounds relaxing. I wish I could get away to the beach like that.
W:(12)Maybe next weekend we can go there together. It’ll be more exciting.
M:(12)That’s great!
